Not sure what you mean by "prior seller listings" exactly.
You can view past 90 days of unsold listings here:
https://k2b-bulk.ebay.com/ws/eBayISAPI.dll?MfcISAPICommand=ListingConsole¤tpage=LCUnsold&pageN...
and past 90 days of sold listings here:
https://k2b-bulk.ebay.com/ws/eBayISAPI.dll?SalesRecordConsole¤tpage=SCSold
May also be alternative Seller Hub pages that do the same. My eBay pages have devolved to 30 or 60 days of lookback.
You can often retrieve listings 90-180 days old by item number, and even up to years old sometimes (but that's really hit and miss, and photos are usually MIA on those)

like this one I sold in Aug 2018: https://www.ebay.com/itm/273374872373?nordt=true&orig_cvip=true
(adding the ?nordt=true&orig_cvip=true to the end of the URL prevents eBay from redirecting your search for the old item to another currently listed one)
